     Except as noted herein, the following conditions and procedures
were observed during the testing:


     In accordance with ANSI C63.4—1992, section 6.1.9, and unless
otherwise indicated in the specific measurement results, the ambient
temperature of the actual EUT was maintained within the range of 10°
to 40°C (50° to 104 °F) unless the particular equipment requirements
specify testing over a different temperature range. Also,     unless
otherwise indicated, the humidity levels were in the range of 10% to
90% relative humidity.


     Prior to testing, the EUT was tuned up in accordance with the
manufacturer‘s alignment procedures. All external gain controls were
maintained at the position of maximum and/or optimum gain throughout
the testing.


     Measurement         results,   unless   otherwise   noted,   are    worst      case
measurements.

NAME OF TEST:                Field Strength of Spurious Radiation

SPECIFICATION:              47 CFR 2.1053(a)

GUIDE:                      ANSI/TIA/EIA—603—1992,    Paragraph 2.2.12

TEST EQUIPMENT :            As per attached page

                              MEASUREMENT PROCEDURE

        A description of the measurement facilities was filed with the
        FCC and was found to be in compliance with the requirements of
        Section 15.38,      by letter   from the FCC dated March   3,     1997,     FILE
        31040/SIT.  All  pertinent  changes will   be          reported        to     the
        Commission by up—date prior to March 2000.

        At first,   in order to locate all spurious     frequencies and
        approximate   amplitudes, and   to  determine proper   equipment
        functioning, the test sample was set up at a distance of three
        meters from the test instrument. Valid spurious signals were
        determined by switching the power on and off.

        In the field, the test sample was placed on a wooden turntable
        above ground at three (or thirty) meters away from the search
        antenna. Excess power leads were coiled near the power supply.

        The  cables  were oriented   in order   to  obtain  the maximum
        response. At each emission frequency, the turntable was rotated
        and the search antennas were raised and lowered vertically.

        The emission was observed with both a vertically polarized and
        a horizontally polarized search antenna and the worst case was
        used.

        The field strength of each emission within 20 dB of the limit
        was  recorded and corrected         with   the   appropriate      cable      and
        transducer factors.

        The worst case for all channels is shown.

        Measurement      results:           ATTACHED FOR WORST CASE

NAME OF TEST:            Emission Masks    (Occupied Bandwidth)

SPECIFICATION:           47 CFR 2.1049(c) (1)

GUIDE:                   ANSI/TIA/EIA—603—1992,       Paragraph 2.2.11

TEST EQUIPMENT :         As per attached page


                              MEASUREMENT PROCEDURE


        The EUT and    test  equipment were set up as     shown            on    the
        following page, with the Spectrum Analyzer connected.


        For   EUTs    supporting    audio   modulation,   the   audio     signal
        generator was adjusted to the frequency of maximum response and
        with   output   level    set   for   #2.5   kHz  deviation    {or    50%
        modulation) .   With     level  constant,    the  signal    level    was
        increased 16 dB.


        For EUTs supporting digital modulation,         the   digital modulation
        mode was operated to its maximum extent.


        The Occupied Bandwidth was measured with the           Spectrum Analyzer
        controls set as shown on the test results.

NAME OF TEST:               Audio Frequency Response

GUIDE:                      ANSI/TIA/EIA—603—1992,      Paragraph 2.2.6

TEST_EQUIPMENT:             As per previous page

                               MEASUREMENT PROCEDURE


        The EUT and test         equipment     were   set   up        as   shown    on     the
        following page.


        The audio signal generator was           connected       to    the   audio       input
        circuit/microphone of the EUT.


        The audio signal input was adjusted to obtain 20% modulation at
        1 kHz,      and this point was taken as the 0 dB reference level.


        With input levels held constant and below limiting at all
        frequencies, the audio signal generator was varied from 100 Hz
        to 50 kHz.


        The response in dB relative to 1          kHz was    then measured,            using
        the HP 8901A Modulation Analyzer.

                                MEASUREMENT _PROCEDURE


        The signal generator was connected to the input of                the   EUT   as
        for "Frequency Response of the Modulating Circuit."


        The  modulation     response  was   measured   for  each    of   three
        frequencies   {(one   of  which   was  the   frequency   of    maximum
        response), and the input voltage was varied and was observed on
        an HP 8901A Modulation Analyzer.


        The   input       level was varied from 30% modulation      (#1.5 kHz
        deviation})      to at least 20 dB higher than the saturation point.


        Measurements were performed for both negative and                   positive
        modulation and the respective results were recorded.

2.      With all power removed, the temperature was decreased to —30°C
        and permitted to stabilize for three hours. Power was applied
        and the maximum change in    frequency was noted within one
        minute.


3.      With power OFF, the temperature was raised in 10°C steps. The
        sample was permitted to stabilize at each step for at least
        one—half hour.   Power was applied and the maximum frequency
        change was noted within one minute.
